Fix query encoding for integer-indexed maps

As reported in #608, integer-indexed maps currently work when passed as
part of the body, but they are reverted to non-indexed maps when passed
in the query.

It turns out that we actually had two problems:

1. We weren't calling our `Util.encode_parameters` on our query
   parameters anywhere, and it's this method will does the integer
   encoding.

2. Even when I fixed (1) by calling `Util.encode_parameters`, Faraday
   would still strip the integer indexes as they were transformed in
   its default `NestedParamsEncoder`.

Here we fix both issues by calling `Util.encode_parameters` and sending
Faraday a custom encoder which bypasses its normal shenanigans.

Unfortunately, this has turned out to be somewhat difficult to test
because the integer-indexed maps also seem to confuse Webmock, which
strips them down to standard maps (I even tried testing against a
string, and it still got it wrong). I did use stripe-mock though to
verify that we are now sending the right payload.

Fixes #608.
